Trilithic offers the “BD” series of filters as a low ripple Chebyshev design which covers the frequency range from 80 MHz to 1000 MHz. Three to eight section designs may be specified with bandwidths ranging from 3 to 40%. This series of filter has moderate power handling capability.
Typical electrical parameters which can be extended or improved include insertion loss, VSWR, & power handling. Consult the factory for applications requiring non-standard frequencies, bandwidths or other parameters.
